| Description |
Sorption of CH(4), N(2), O(2), and Ar in ZSM-5 with different SiO(2)/Al(2)O(3) ratios was studied by volumetric measurements and grand canonical Monte Carlo simulation. Sorption capacity for all the gases studied was observed to decrease with in increase in the SiO(2)/Al(2)O(3) ratio of ZSM-5. The sorption selectivity of CH(4) over N(2) increases, whereas sorption selectivities of N(2) over O(2) and Ar decrease with an increase in the SiO(2)/Al(2)O(3) ratio of ZSM-5. ZSM-5 with SiO(2)/Al(2)O(3) of 900 showed higher selectivity for CH(4) over N(2), whereas the SiO(2)/Al(2)O(3) ratio of 25 showed higher N(2) selectivity over O(2) and Ar. The heats of adsorption for CH(4) and N(2) decrease and that for O(2) and Ar remain unaffected with an increase in SiO(2)/Al(2)O(3) ratio of ZSM-5. The values of Henry's constant were also calculated for CH(4), N(2), O(2), and Ar for adsorption in ZSM-5 having varied SiO(2)/Al(2)O(3) ratio. The experimental results were compared with theoretically calculated data using grand canonical Monte Carlo (GCMC) simulation. Simulation studies expectedly showed the proximity of N(2) molecules to the sites occupied by extraframework sodium cations.
